The 20th International Workshop on Randomization and Computation(RANDOM'2016) and the 19th International Workshop on ApproximationAlgorithms for Combinatorial Optimization Problems (APPROX'2016) willbe held on September 7-9, 2016 at the Institut Henri Poincaré, Paris,organized by IRIF (CNRS and Université Paris Diderot).RANDOM'2016 focuses on applications of randomness to computational andcombinatorial problems while APPROX'2016 focuses on algorithmic andcomplexity theoretic issues relevant to the development of efficientapproximate solutions to computationally difficult problems.

TOPICS:Papers are solicited in all research areas related to randomization andapproximation, including but not limited to:

SUBMISSIONS:Abstract Format: Electronic submissions are solicited. Please consultthe following servers:For submission of APPROX papers:http://www.easychair.org/conferences/?conf=approx2016 [1]For submission of RANDOM papers:http://www.easychair.org/conferences/?conf=random2016 [2]Note: You will be asked to login using an EasyChair account.Instructions on how to register for such an account are available at thesubmission servers (you may also have an old account from a previousconference submission).The submission must be received by 15:00 (PDT) of April 19 for yoursubmission to be considered.Submission Format: Submissions should start with the title of the paper,each author's name, affiliation, and e-mail address, followed by a briefabstract of the results to be presented. This should then be followed bya technical exposition on single-spaced pages on letter-size paper,using reasonable margins and at least 11-point font. The first 10 pagesshould contain the main ideas and techniques used to achieve the resultsincluding motivation and a clear comparison with related work (notincluding the references). There is no page limit but any materialbeyond the first 10 pages will be read at the sole discretion of theprogram committee.Simultaneous submission to other conferences with published proceedingsis not allowed.

PROCEEDINGS:Accepted papers will be published in the online proceedings of theconference in the Leibniz International Proceedings in Informatics(LIPIcs) series, based at Schloss Dagstuhl. This guarantees perennial,free and easy electronic access, while the authors retain the rightsover their work.
